Development of electrodes for a hybrid anode of Li-ion battery and super
capacitor
Nano-honeycomb diamond exhibits charge and discharge behavior toward electrochemical
double-layer when using electrolyte containing Li ions.
Our group has realized hybrid electrode material with high energy
density and high specific power having the combination function of
the electric double layer capacitor and the Li ion battery when carbon
nanotubes, which exhibit the behavior of intercalation, are introduced
into
the pores of nanohoneycomb diamond.
